The relationship between effects of injury on right inferior precentral cortical thickness and blood-based biomarkers

	Sub-acutely injured rugby players (n = 14)	Controls (n = 15)
Mean GFAP pg/mL (SD)	58.59 (22.6)	48.03 (2.23)
GFAP β-coefficient for right inferior precentral sulcus cortical thickness (P-value)	0.0032 (P = 0.0012**)	−0.0035 (P = 0.041*)
Mean NfL pg/mL (SD)	10.29 (6.06)	4.95 (2.23)
NfL β-coefficient for right inferior precentral sulcus cortical thickness (P-value)	−0.0013 (P = 0.65)	−0.0035 (P = 0.71)

All analyses were additionally corrected for age and sex. GFAP, glial fibrillary acidic protein; NfL, neurofilament light; SD, standard deviation. *P < 0.05; **P < 0.06.
